I should hope the chassis is stronger then your last spinner James, and ALOT safer to handle.

eh? nothing wrong with my last spinner dave, it never broke.
assuming you are reffering to tantrum as its the only spinner of mine you have seen, and only one of the 16 featherweight spinners ive built.
and no, none of them broke either, well, ive had no complaints anway.

Rather than opening a new thread ill just post here
I have been on a bit of a break from robots and after seeing some videos of recent events it has rekindled my interest . I am making a drum spinner - nearly all the components are gathered and just need to be machined . My main concern is the drum and the bearings . Should I have the bearings inside the drum with a stationary shaft OR should i have the bearings in the bulkheads and a stationary shaft connected into the drum ? I can see both ways have its up and downside but i cant really pick one. Any suggestions ?

My drum has bearings in the drum with a fixed axle, if this helps.

Fixed axle, because of the pure reason that being fixxed in place adds to the chassis strength. Might not be improtant in your design but it was needed in Conundrum,

I was deliberating the same thing when I was thinking about the design of my drum, and although its not actually made yet, Ive opted to go for the fixed axle too.

I bought bearings for it with the intention of mounting them in the bulkheads, but I liked the fact that having a fixed axle would add more strength overall.

In terms of maintenance its also probably easier to replace a shaft thats fixed to the chassis than it would be if the shaft was fixed to the drum

Another advantage of a fixed axle as far as I see it, is that if you tweak your chassis it is unlikely stop your weapon, as a fixed axle will remain rigid. But it you had bearings in the chassis they could lock up because of the axle miss alignment.

(Btw everyone : Im still building and around, its just taking awhile to get my two new spinners built and working without shearing parts. So ill be appearing at events soon enough.)
